A couple of months ago it was indicated that there was ongoing work around Apache Jena 3 support. Any updates on the progress, or proposed timeline? Jena 3.x support would be really helpful for some projects I'm working on, would love to tryout even an early release.

We have recently released support for Apache Jena 2.11.2. Internally, we have a working prototype with Apache Jena 3.1.0. Things are looking good but we have to finish many rounds of testing because we can release it. If you want to test an internal early release, please file an SR (and send the SR# to alan dot wu at oracle dot com).
